[sf_giants15]

Today I was dispatching Dorota. Wshodnia accidently asked for permission for direction change which I accepted. After calling him on the phone he decided to take back the direction change since no train was coming. The white  arrow flashed again and you could hear the ringing noise but i didnt know how to accept it. I tried the "Poz" button but it didnt work
